Description
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates, in general, to an educational device
for use in teaching writing skills and, more specifically, the use
of pencil, pen, and/or brush in free-hand forming phonetic,
numerical or pictorial letters and characters.
2. Description of the Related Art:
Various patents have heretofore issued on improved writing aids and
the like. See, for example, Higbee, U.S. Pat. No. 1,143,393;
Lorber, U.S. Pat. No. 1,887,161; Lucero, U.S. Pat. No. 3,382,592;
Paul, U.S. Pat. No. 3,731,402; Chandler, Australian Pat. No.
101,845; and Weiss, French Pat. No. 2,516,893. None of the above
patents disclose or sugeest the present invention.
Grooved or through-cut lettering guides have long been available
and currently are marketed under various brand names such as
"Leroy", "Tech-Graphic", "Wrico", etc. Such lettering guides are
100% mechanically guided, and thus are not designed to be used in
the primary teaching of letter forms and names and are not suited
for teaching young children. More specifically, the chief use for
such lettering guides is for the preparation of maps, presentation
drawings in the mechanical and construction trades, and for
lettering drawings which will be reprinted thousands of times, such
as the wiring diagrams found on major household appliances.
The familiar ABC blocks are usually the first letter-teaching
devices given to a child. However, such blocks do not teach
anything about copying the letters and the child typically loses
interest in the blocks before becoming interested in lettering.
Educational television is currently achieving excellent success in
the teaching of both the shapes and the sounds of letters. However,
such educational television reaches only a fortunate segment of the
world's population, is entirely visual in nature and thus does not
provide manual or hand training. Further, the student can respond
only while a particular exercise is being shown and the student may
have to compete with other family members for viewing time,
etc.
The most popular means of pre-school child education requires that
the teacher, usually a parent, properly place a pencil into the
child's grasp, then place the teacher's hand over that of the
child, and guide the child's hand while an attempt is made to
produce an acceptable letter.
Though in use since alphabets were first invented, the method, a
one-on-one operation, remains very slow and inefficient. Also, the
modern trend is for both parents to accept employment outside the
home, thus drastically reducing the time available for child
pre-education. Further, parents are leaving their children with
child-care enterprises which of course want as many children as
their operation permits, thus resulting in groups where the
one-on-one teaching method is inapplicable.
Hence the invention hereinafter disclosed.
SUMMARY OF THE INVENTION
The present invention is directed toward providing a device for
teaching basic writing skills and, more specifically, the ability
to form characters, such as alphabetic letters, pictorial
characters and the like with a pen, pencil or brush.
The educational device of the present invention is for use in
teaching manual cursive writing and hand-printing skills to
students. The device includes, in combination, a board member
having a plurality of grooves therein, each of the grooves forming
at least a portion of a specific character; and a tracing stylus
having a staff for being held by a student, having a tracer element
coupled to the staff and for extending into at least one of the
grooves to follow at least one of the grooves and the guide the
movement of the staff when moved properly by the student, and
having a contact plate for engaging the board member when the
tracer element extends into one of the grooves.
Advantages of the device of the present invention over the usual
present method and devices include:
1. Exact repeated definition of any selected character when
properly traced.
2. Manual guiding of the pupil's hand will become unnecessary as
soon as the pupil learns to follow the grooves with the contact
plate engaging the board member to hold the stylus square with the
board member.
3. More students can be supervised by one teacher.
4. One pupil can help another.
5. A pupil can use the device as a form of amusement.
6. Pupils will develop greater uniformity in freehand work.
7. Older students can use the device with even greater
facility.
8. One device can be used by an entire family or village.
9. The device can be used by either right or left handed
students.
10. The device is inherently rugged and will require only minimal
care for long usage.
11. The device is relatively inexpensive.
12. The device device requires no battery or other electrical
source.
13. The device can be used to teach office machine keyboard
layout.
14. The device enables blind students to learn quickly to make
standard characters.
15. The device is excellent for immigrants from a pictorial culture
to a phonetic culture.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
A preferred embodiment of the educational device 11 of the present
invention is shown in FIGS. 1-10. The device 11 is used in teaching
basic writing skills and the like. The device 11 includes, in
combination, a board member 13 having a plurality of characters 15
thereon, and a tracing stylus 17 for use in tracing one or more of
the characters 15.
The board member 13 is preferably formed as a substatnially flat,
rectangular plate having a substantially flat first side 19 and a
substantially flat second side 21. The characters 15 are preferably
provided on both the first and second sides 19, 21 of the board
member 13. The characters 15 are preferably formed by grooves 23
molded, cut or otherwise formed into the first and second sides 19,
21 of the board member 13 in the shape of the various specific
characters. The grooves 23 may form alphabetical, numerical, and/or
pictorial characters in any language or languages and in any genre,
alone or in any combination, and in any style or styles. An
important feature of the present invention as shown in FIG. 3 is
that the grooves 23 may form an office machine format, e.g., the
typical "qwerty" typewriter, computer keyboard layout, to allow a
student to become familar with such office machine formats at an
early age, etc. Each groove 23 is shown as substantially V-shaped
in cross section with a rounded bottom 25 to avoid sharp
stress-raising corners and to minimize the total thickness of the
board member 13. The board member 13 may be made of any desired
material having good workability, non-toxicity, color, and cost
acceptability such as, for example, one or a combination of the
various thermoplastic resins available from du Pont and several
others. The characters 15 may be molded, pressed, engraved or cut
into the board member 13. The color of the board member may be
selected for good visibility and appeal. The outer edges of the
board member 13, the walls and the bottom of the grooves 23 may be
painted or otherwise colored to contrast with the sides 19, 21,
etc.
The tracing stylus 17 preferably includes an elongated staff or
handle 27 for being held by the student, a tracer element 28 having
a tracer point 29 for extending into the grooves 23 of the
characters 15, and a body 31 attached to one end of the handle 27
for securing the tracer element 28 to the handle 27. The tracer
point 29 is preferably conical and preferably has a rounded end,
the radius of which is preferably slightly greater than that of the
rounded bottom 25 to allow the sloping sides of the tracer point 29
to slidably engage the sloping sides of the grooves 23 while
preventing the end of the tracer point 29 from contacting the
rounded bottom 25 of the grooves 23. Due to such construction,
downward pressure on the tracer element 28 causes the tracer point
29 to contact the sides or V-slopes of the grooves 23, which in
turn causes the tracer element 28 to assume the desired upright
attitude in the user's grasp. Also, the same construction provides
a considerable wear factor before the tracer radius finally begins
to bottom out in the grooves 23, thus extending the useful life of
the board member 13 (if the tracer point 29 bottoms out, further
groove wear would cause the stylus 17 to become wobbly in the
user's hand, thereby becoming a distraction). The included angle of
the conical tracer point 29 is preferably approximately that of the
grooves 23. The tracing stylus 17 preferably includes an elongated
outrigger beam 33 for being secured to the body 31 and a marking
means 35 for being secured to the outrigger beam 33 for allowing
the student to write or draw the characters 15 on a piece of paper,
or the like, as the characters 15 are traced with the tracer point
29. More specifically, the outrigger beam 33 preferably has a first
end 37 for being secured in an adjustable manner to the body 31 and
a second end 39 for being secured to the marking means 35. The body
31 preferably has an aperture 41 therethrough for slidably
receiving the first end 37 of the outrigger beam 33. The marking
means 35 preferably includes a body 43 having an aperture 45
therethrough for slidably receiving the second end 39 of the
outrigger beam 33. The apertures 41, 45 and the outrigger beam 33
preferably have corresponding polygonal cross-sectional shapes to
prevent rotation of the outrigger beam 33 within the apertures 41,
45. A screw 47 may be provided to securely clamp the outrigger beam
33 to the body 43 as will now be apparent to those skilled in the
art. Another screw may be provided to securely clamp the outrigger
beam 33 to the body 31 as will now be apparent to those skilled in
the art (the tracer element 28 may, in fact, form the screw to
secure the first end 37 of the beam 33 to the body 31 as clearly
shown in the drawings). The body 43 of the marking means 35
preferably includes an aperture 49 for allowing a marking element
51 to be removably secured thereto. The marking element 51 forms an
integral part of the marking means 35 and may consist of a typical
commercially available technical pen or pencil such as certain
models of the Koh-I-Noor technical pens produced by Rapidograph
Inc. of Bloomsbury, N.J.. A screw 52 may be provided to secure the
marking element 51 within the aperture 49 as will now be apparent
to those skilled in the art. The various screws amy be the
allen-head or similar type to prevent dismantling of the tracing
sytlus 17 with more common tools.
The first side 19 of the board member 13 may be divided generally
into a first half 53 and a second half 55 with the first half 53
preferably including characters 15 forming the entire lower and
upper case alphabet and Arabic numbers in various sized and with
each character 15 arranged substantially vertically and with the
second half 55 preferably including characters 15 forming the
entire lower and lower case alphabet and Arabic numbers, etc., in
various sizes and with each character 15 arranged slanted (see FIG.
1). The second side 21 of the board member 13 may also be divided
generally into a first half 57 and a second half 59 with the
characters 15 on the first half 57 forming the typical keyboard
layout of typical office machines (typewriter, computer, adding
machine), telephones, clock faces, etc. and with the characters 15
on the second half 59 forming typical road signs, etc. The
characters 15 on the first and second halves of each side 19, 21
are preferably rotated 180 degrees relative to one another so that
the uppermost half will be oriented in the "upright" position and
the tracing stylus 17, when in use, will always be associated with
the upper half of the board member 13 in order for the student's
hand and at least a portion of the forearm to always rest on a
lower portion of the board member 13 when tracing one of the
characters 15 to prevent the board member 13 from moving when the
student exerts sidewise pressure on the board member 13 with the
tracing stylus 17, etc.
Wherever applicable, a printer's division line 64 may be indented
into the sides 19, 21 of the board member 13 between the first and
second halves thereof to give visual as well as tactile (for blind
pupils) indication of the limits of the different character areas
of the board member 13.
The board member 13 may have one or more depressions or channels 65
in one or both sides 19, 21 thereof, and the device 11 may include
one or more auxiliary board members 67 for being attached to the
board member 13 by being snapped into, glued to or otherwise
secured to a channel 65. Each auxilary board member 67 may have
indicia thereon for identifying the ownership and/or type of the
specific board member 13, etc. Thus, while for very large orders,
such as state or federal agencies, the owners insignia could most
economically be built directly into the mold, the above
construction provides every retail customer an easy way to add
identification to the board member 13. A clear plate 69 may be
provided for being snapped into a channel 65 over an auxiliary
board member 67 to protect the board member 67, etc, (see FIG. 5).
The channel 65 may be located adjacent the division line 64 as
clearly shown in FIG. 3.
A modified embodiment of the tracing stylus of the device 11 is
shown in FIGS. 11-13 and is identified by the numeral 2.17. The
tracing stylus 2.17 is similar to the tracing stylus 17 and
includes a staff 2.27 for being held by a student and a tracer
element 2.28 coupled to the staff 2.27 and having a tracer point
2.29. The tracer point 2.29 is preferably substantially cylindrical
with a rounded end or point for safety. A modified embodiment of
the board member of the device 11 is shown in FIGS. 12 and 13 and
is identified by the numeral 2.13. The board member 2.13 is similar
to the board member 13 and has a plurality of characters 2.15
thereon formed by grooves 2.23 molded or cut or otherwise formed
into the face surfaces of the board member 2.13. The grooves 2.23
preferably have substantially straight sides 2.23' and a
substantially flat bottom 2.23" for receiving the substantially
cylindrical tracer point 2.29 as clearly shown in FIG. 13. The
outer edge of each groove 2.23 have small chamfers 2.23"' to
facilitate entry of the tracer point 2.29 and to give a heavier,
more visible character outline. More specifically, each groove 2.23
is preferably substantially funnel-shaped in cross section with a
flat or slightly convex bottom 2.23" and preferably a small fillet
where the bottom 2.23" joins the sides 2.23'. The sides 2.23' are
preferably substantially parallel with only enough draft to insure
satifactory withdrawal from the forming tooling during manufacture.
The small chamfers 2.23"' complete the funnel shape of the grooves
2.23. A unique feature of the tracing stylus 2.17 is the addition
of a contact plate 2.71 for engaging the surface of the board
member 2.13 when the tracer point 2.29 is in a groove 2.23 to keep
the stylus 2.17 square with the board member 13; to prevent
twisting of the staff 2.27 which can damage the grooves 2.23; to
limit penetration of the tracer point 2.29 into the grooves 2.23
with consequent wear; and to allow the stylus 2.17 to move smoothly
and easily while characters 2.15 are being traced, etc. The board
member 2.13 may be provided with parallel grid lines 2.73 between
the characters 2.15 for use in properly aligning and maintaining
alignment of the tracing stylus 2.17 relative to the characters
2.15. More specifically, the contact plate 2.71 is preferably
substantially square whereby the student can visually align the
straight edges thereof with the grid lines 2.73 to thus keep the
stylus 2.17 square with the board member 2.13 which will aid the
student in acquiring the habit of making vertical freehand work.
The staff 2.27 preferably has an offset portion 2.75 to provide
open visibilty at the tracer element 2.28. The stylus 2.17 is
preferably provided with a staff 2.27 with an offset portion 2.75
as shown in FIG. 12 for use by right hand students and a staff 2.27
with an offset portion 2.75 extending opposite from that shown in
FIG. 12 for use by left hand students as will now be apparent to
those skilled in the art. The staff 2.27 is preferably pivotally
coupled to the tracer element 2.28 and contact plate 2.71 to allow
the angle thereof to be adjusted to suit the student. Thus, the
stylus 2.17 may include a pair of spaced lugs 2.77 attached to and
extending upwardly from the upper surface of the contact plate 2.17
and the staff 2.27 may be attaached thereto by a screw 2.79. Each
lug 2.77 preferably has an aperture for receiving the screw 2.79
and the aperture opposite the head of the screw 2.79 is preferably
threaded as will now be apparent to those skilled in the art. The
tracer element 2.28 may consist of a screw for extending through a
thread aperture 2.81 in the contact plate 2.71 with the distal end
thereof machined or otherwise modified to form the tracer point
2.29. The contact plate 2.71 is preferably constructed of a plat,
transparent material such as plastic or the like with the corners
thereof rounded for safety. The contact plate 2.71 preferably haas
a relieved portion 2.83 in the area which a student will look as he
seeks to insert the tracer point 2.29 nto the groove 2.23 of the
selected character 2.15. The relieved portion will prevent the face
surface of the plate 2.71 from becoming scratched and dull due to
environmental dust and the like and which might hinder vision
therethrough. The relieved portion 2.83 will allow unobscured
vision even after the contact plate 2.71 becomes worn over its
contact area. The tracing stylus 2.17 may be adapted to receive to
iutrigger beam 33 and marking means 35 in any manner now apparent
to those skilled in the art. Thus, for example, the contact plate
2.71 may be provided with a boss member or the like (not shown)
having a polygonal shaped aperture therethrough for receiving the
outrigger beam as will nowe be apparent to those skilled in the
art. The funnel shape of the grooves 2.23 provides four significant
advantages in the design of the board member 2.13 and the tooling
for its manufacture: (1) The chamfers 2.23"' and width across the
grooves 2.23 for greater visibility through the contact plate 2.71
of the stylus 2.17; (2) The chamfers 2.23"' add width across the
grooves 2.23 which makes for easier entry of the tracer point 2.29;
(3) The chamfers 2.23"' reduce the danger of mutilating the grooves
2.23 if the user elects to use an unsuitable point for tracing,
such as that of a ball-point pen; (4) The chambers 2.23"' are
preferably formed by corresponding angular fillets on the tooling,
where they add resistance to fin breakage during handling and
manufacture of both the board 2.13 and the tooling.
The use and operation of the present invention is quite simple. For
the first time user, all the teacher has to do is to see that the
pupil holds the tracing stylus 17 (without the outrigger beam 33
and marking means 35) in the correct attitude with the tracer point
29, 2.29 within the proper or selected groove 23, 2.23 and to see
that the pupil traces the character 15, 2.15 in the proper
rotational direction, etc., with the contact plate 2.71 engaging
the surface of the board member 13, 2.13. After satisfactory pupil
progress, the teacher may attach the outrigger beam 33 and making
means 35 to the body 31 of the tracing stylus 17 or to the contact
plate 2.71, etc., and the paper 61 may be placed next to the board
member 13. With the marking means 35 properly adjusted, a traced
character 63 will be formed on the paper 61 when the character 15,
2.15 is traced as will now be apparent to those skilled in the art.
The pupil will learn to first get the tracer point 29, 2.29 in the
proper groove 23, 2.23, then to lower the marking means 35 into
contact with the paper 61, to hold the tracing stylus 17, 2.17 in a
vertical plane parallel to the longer sides of the board member 13,
2.13, and to use the entire arm when guiding the stylus 17, 2.17
instead of flexing the fingers, thus learning basic requirements of
good penmanship, etc. A rubber or rubber-like plastic board or pad
(not shown) having a substantially smooth top surface and having a
plurality of downwardly extending flexible papillae on its bottom
surface may be provided for resting on top of the board member 13,
2.13 or desk top or both, and for supporting the student's arm as
the device 11 is used. The pad may be about 6 inches wide by 15
inches long and will move in any horizontal direction in response
to the student's arm movement by flexing of the papillae. The
present invention thus provides an intermediate step between 100%
mechanically guided lettering using prior lettering guides and 100%
free-hand lettering.
Although the present invention has been described and illustrated
with respect to a preferred embodiment and a preferred use
therefor, it is not to be so limited since modifications and
changes can be therein which are within the full intended scope of
the invention.
